Silin (1995: 104) argued that such an overemphasis on developmental ways of knowing children creates "a minefield continually being reseeded with new points of danger" for adults. If adults need to know all these theories of the child before acting wisely for their good and for their success then we must constantly risk unsuccessfully and foolishly as we plan for children at particular inappropriately, theories stages of their development. Silin (995) pointed to several developmental of the child that place the adult in danger of getting it wrong, including attachment theory, cognitive theory and theories of co-construction. To understand Silin's point let's turn to John Bowlby's 1950s theories of attachment and maternal deprivation.
